This series of products is a new generation of environmentally friendly high-performance polycarboxylate superplasticizer, the series of PC flake products has homogeneous indicators that meets ASTM C 494 Type B,D,F,G international standards. It is suitable for high volumetric stability, strong durability, high workability of the concrete. It can be widely used in ordinary pumping concrete and high-strength concrete, self-compacting concrete, plain concrete, precast concrete, and other high-performance concrete. It has excellent performance.

Compared with the second generation naphthalene based series,water reducing rate has greatly improved, which greatly saves the production cost and transportation cost, and is suitable for long-distance transportation. Compared with the traditional powder Polycarboxylate Superplasticizer, it has obvious performance and cost advantages.

Product Features

** Water-reducing type PC-808:

Has a high water reduction and dispersion, for the formula C30 above the high-grade, high-performance, self-leveling concrete provides a guarantee, enhance the effect of obvious, minimal to no shrinkage, good economic results.

Concrete hardening and durability, compress strength of each age, can be used for the formulation of various types of prefabricated, pipe piles, pumping, and other high-strength high-performance concrete.

** High Slump Retention type PC-708

Excellent performance, can be used during the summer under high temperature conditions of construction of large volume of concrete, self-compacting concrete.

With a wide range of adaptability, can solve a variety of factors caused by slump loss concrete problems. For the pumping of the concrete, the long distance transportation, and the medium and low standard concrete formulation.

** Retarder Type PC-608

Has a good cohesion, suitable for solving some of the cement when adaptability is not good, less cementitious material concrete formulation, can significantly improve the retention of concrete slump value and its cohesion, and not easily segregated, removes bleeding.

It is suitable for solving the problem of excessive loss of concrete which can not be overcome because of the high content of clay, the long distance of transportation, and the high temperature. Also commonly used in the formulation of low slump, high retention requirements of the concrete.

Uses

It is suitable for ready-mix and cast-in-place concrete in the formulation of precast concrete, retarded concrete, large flow concrete, self-compacting concrete, mass concrete, high performance concrete and plain concrete, various industrial and civil construction.

It is suitable for industrial and civil engineering, public infrastructure, hydroelectric engineering, and concrete ready-mix products that prefabricated and RMC concrete, reinforced concrete and prestressed concrete.

Dosage and Safety Precautions

Recommended dosage of 0.2 to 0.5% of the amount of cementitious material, the general recommended dilution and then use. When using this product, users should use the necessary concrete mix design test according to the specific construction conditions to determine the optimum dosage.

This product is ready for use after evenly mixed with water.

For example: If you want to make 1 liters of PC-F (50%), the density of 1.05. is the first need to weigh on the electronic balance of PC Flake of 525 grams, and then add to 525 grams of water, after mixing evenly, you can get PC-F (50%) – 1 liters.

This product can be used alone, but also with other varieties of polycarboxylate superplasticizer used in combination.

It must not be used in combination with naphthalene superplasticizer. When used in combination with other types of admixtures, the concrete compatibility should be checked first.

Winter construction of concrete, it is recommended to take surface frost insulation measures, according to the construction specifications to strengthen conservation, to prevent the freezing of concrete.

Packaging and Storage
